NTRNAL-COMBUSTEGN ENGINE.

Application filed September 25, 1918.

To all whom t may concern.'

Be it known that I, Ponri Us ll. lVEELER, a citizen of the UnitedStates, and a resident of Peoria, in the county ot' Peoria and State ot'Illinois7 have invented certain new and useful Improvements inlnternal-Combustion Engines, of which the following' is a full. clear,and exact description, reference beinghad to the accompanyingq drawinforming a part ot' this specification.

ly invention relates more particularly to that class ot' internalcombustion engines operatinp, upon the two-stroke-cycle principlewherein a power impulse is imparted to the piston for every two strokesthereof.

One object ot' my invention is to so arrange the rvarious parts of theengine that the suctiori stroke thereof will he continuous during`substantially a halt revolution of the crank shaft.

Another object of my invention is a provision of means whereby a portionot the charge sweeps the ignition element thus insuring' the properignition of the charge.

Another object ot' my invention is to arrange the Various parts of theengine so that they are easily accessible tor repair, renewal orinspection, should occasion arise.

Other objects of my invention will appear and be described in thespecification.

The noveltyvoic my invention will be hereinafter more t'ully set forthand specifically pointed out in the claims.

ln the accompanyingdrawing Fig-ure l is a sectional end elevation of anengine emparts being shown in their proper relation and position at thepoint of ignition.

Fig. ll is a View similar to Fig: l, some ot' the parts being shownbroken away, the' position and relation of the parts beiner properforaposition about midway on the suction and compression stroke.

The saine numerals ot reference are used to indicate identical parts inboth figures.

To illustrate one form ol engine in which my invention may be embodied,l represents a cylimler structure composed ot the inner cylinder wall Q,water ljacket wall- 3, valve pocket 4, and other parts to be laterdescribed. 'lhe cylindrical' piston r mounted within the cylinderfandconnected by meansI ot' connecting rodttivto the (granit i cra nl; case8. The upper portion ofthe cylindrical pis ton is provided with exhaustports 9, suc- Specification of Letters Patent.

tion and transfer ports 10, and head 11, this head being provided withmg anda stuling box 12 and the central opening in tube 13 is passed, thetube the member 14, and carrying 15 at its lower end.

The member 1112 is secured to the upper portion of the cylinderstructure `as by means of cap screws 16. The valve pocket 4 is providedwith the valve 17 which may be the usual form ot' puppet valve, or anyother suitable form of valve and is provided w1th a downwardlyextendingn stem 18 and spring` 19 which serves to normally hold thevalve 17 against its seat. The valve actuating mechanism comprises alink 2O which is connected to the connecting' rod 6 at one end and tothe bell crank 2l at the other end, the bell crank 21 beingmounted uponthe valve lifterr guide 22 as clearly shown, the guide carrying thevalve lifter 23 which is adjustable as by means of the cap nut 24 andlock nut 25 so that the parte may be set to insure the proper operationof the valve 17.

At the head end of its travel one of the exhaust ports 9 of thecylindrical piston 5 registers with the ignition port 26 as shown thehead 11, a being held in a piston head vin Fig. l and any suitable formof ignition device such as the spark plug 27 may be provided for theignition of the char e, while at the lower end of the travel of t ecylindrical piston 5 one of the exhaust ports S) registers with theexhaust port 28 through which the spent gases pass to the exhaustmanifold 29. v

An annular inlet port 30 is formed in the cylinder structure andcommunicates with the valve pocket 4 and with the inlet and transfer ton5.

lt is to he noted that the inlet and transfer ports 10 are ot suchlength and location thaft immediately after the beginningf of theregistration of the exhaust portl with the exhaustpassage 28, the loweredge ot thc inlet wand 'transfer ports 1() pass below thelower edge oithe pistonA head 15 to permit the charge to transfer as will be laterdescribed. v lt is also to he noted that the piston head 'l5' is a-tall'tiines stationary with relation to the cylinder structure andtofacilitate the control ot' its temperature during lthe operation oi theengine it may be provided a central open-j through which,

ports l() ot the cylindrical pis-,

n ileeeee ing cylinder and a combustion space, a snp port for saidstationary piston head seid support passing` through the chargingportion of said cylinder piston7 e removable head sun' rounding saidsupport and carried'by said cylindrical piston, cooling medium inleiJand outletpassages in said support and communioating with a coolingmedium space in said stationary piston head, a valve in the inletpassage of seid cylinder structure, and oonnections between a movingpart of the engine and a valve lifter whereby said valve may be raisedfrom its seat during the suction stroke of the engine.

In an internal combustion engine the combination of a cylinderstructure, e eyl lindrical piston therein and connected edja- 'cent oneend to operate a crank shaft, a removable head in the drical piston-'andarranged stuing box, a support carried by other end ofV the eylm` liecylinder srnoeurej e 'nbe depending from the support and passing throughthe stuiiingbofi of the head of the eyliiiidrieal piston, a piston beadcarried by alle lower end of Jche tube and provided with ii eenlingmedium chamber the piston liead dividing the cylindrical piston intocharging and combustion Cylinders, ineens for cirenlating2 2L coolingmedium through die piston head and its tubular support, in admission andtransfer port in tbe cylindrical piston, an ignition device carried bythe Cylinder strueture and registering with the transfer port during thetransfer of :i charge whereby the charge will sweep the ignition device,and an ignition and exhaust; port registering with the ignition devicefor the "l the charge and with an exhaust port in the cylinder structurefor the exhaust of the eo charge.
